Claims

[Claims for Utility Model Registration] 1. An internal combustion engine equipped with an electromagnetic control valve for controlling the internal combustion engine on the clean side of an air cleaner, wherein the air cleaner is a vehicle-mounted air cleaner. 2. The internal combustion engine according to claim 1, wherein the electromagnetic control valve is an electromagnetic negative pressure control valve that controls input negative pressure of a negative pressure operated actuator for increasing the idle speed of the engine. institution. 3. The negative pressure actuator is provided with a negative pressure chamber that displaces a diaphragm linked to a throttle valve of the engine intake system in accordance with input negative pressure, and the negative pressure chamber is connected to a negative pressure transmission pipe on the one hand. an atmospheric air introduction pipe connected to the engine intake manifold via the engine so as to reflect the intake pipe negative pressure in the negative pressure chamber, and whose flow rate is controlled by the electromagnetic negative pressure control valve. The internal combustion engine according to claim 2, wherein the internal combustion engine is connected to the clean side of the vehicle-mounted air cleaner through the air cleaner. 4. The negative pressure actuator includes a negative pressure chamber that changes a diaphragm linked to a throttle valve of the engine intake system in accordance with input negative pressure, and the electromagnetic negative pressure control valve operates through an atmospheric port. an internal valve chamber that communicates with the clean side of the air cleaner and the intake manifold of the engine via a negative pressure port and a negative pressure transmission pipe; and either the atmospheric port or the negative pressure port housed within the valve chamber. the internal valve chamber of the electromagnetic negative pressure control valve is communicated with the negative pressure chamber of the negative pressure actuator through a second negative pressure transmission conduit. An internal combustion engine according to claim 2 of the utility model registration claim. 5. The internal combustion engine according to claim 1, wherein the electromagnetic negative pressure control valve is an electromagnetic auxiliary air flow rate control valve that controls the flow rate of auxiliary air supplied to the intake manifold of the engine.
